Before the Derby, Fergie Worrying Line Of Manchester United

Manchester - This weekend, Manchester United will face the derby against Manchester City. MU has not felt strong defense, Sir Alex Ferguson is worried his team will be a hive goal of the opposing team.

Premier League week-16 will be to bring together the two clubs from Manchester City at Etihad Stadium on Sunday (09/12/2012) evening hrs.

In the last season, at home to City meeting was ended 1-0 to the host advantage. But when the two teams face each other at Old Trafford, goalkeeper David De Gea burglarized six times by the City players.

Fergie fears on the back line based on appearance when Manchester United face Reading in the last 15 weeks. Wicket 'Red Devils' burglarized three times by Reading players within 23 minutes - although in the end Manchester United still won 4-3.

MU defense is considered quite fragile at this season. Premier League runs until 15 weeks, Chelsea's goal was breached 21 times, or the worst of the three top teams in the standings.

"If we played like that (like against Reading,-ed) on Sunday, then God knows what will happen to us," said Fergie was quoted as saying by The Sun.

"It's alarming, it's so full, there's no doubt about it. I do not even remember we conceded a lot of goals before Christmas."

"When you see a player who can play City - Balotelli, Dzeko, all players who are tall, it will be a big challenge. Roberto Mancini and I have to think more deeply about the choice of players and tactics," he said.
